Android 如何从屏幕底部向上滑出一个view

我的实现方式是使用Android 中的dialog实现的，直接看下面的代码步骤

1、定义dialog的布局

<?xml version="1.0" encoding="utf-8"?>

2、定义一个类，然后直接继承dialog

package com.dx.jingle.dialog;import android.app.Dialog;import android.content.Context;import android.os.Bundle;import android.view.View;import android.widget.Button;import android.widget.EditText;import android.widget.RadioButton;import android.widget.TextView;import androidx.annotation.NonNull;import com.dx.jingle.R;import com.dx.jingle.bean.DishesVoBean;import com.dx.jingle.bean.ShoppingCartBean;import com.dx.jingle.util.MainUtil;import java.math.BigDecimal;public class HomeShopDialog extends Dialog {    private Context context;    private DishesVoBean dishesVo;    private OnItemClickListener onItemClickListener;    private String strShop;    public void setOnItemClickListener(OnItemClickListener onItemClickListener) {        this.onItemClickListener = onItemClickListener;    }    public HomeShopDialog(@NonNull Context context, DishesVoBean dishesVos) {        super(context);        this.context=context;        this.dishesVo=dishesVo;    }    public HomeShopDialog(@NonNull Context context, int themeResId, DishesVoBean dishesVo) {        super(context, themeResId);        this.context=context;        this.dishesVo=dishesVo;    }    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        //设置布局        setContentView(R.layout.dialog_home_shop);    }    }    public interface OnItemClickListener{        void onBtnPlusClick(View view, ShoppingCartBean data, DishesVoBean datas);    }}

3、然后自定义一个点击事件

 //设置点击事件        rvReserveHomeAdapter.setOnItemClickListener(new RvReserveHomeAdapter.OnItemClickListener() {            @Override            public void onBtnPlusClick(View view, DishesVoBean data, int position) {                //1、初始化Dialog                HomeShopDialog dialog=new HomeShopDialog(mActivityContext,R.style.DialogTheme,data);                //获取Dialogwindow对象        Window window=dialog.getWindow();        //设置弹出位置        window.setGravity(Gravity.BOTTOM);        //设置动画        window.setWindowAnimations(R.style.dialog_menu_animStyle);        //设置对话框大小        window.getDecorView().setPadding(0,0,0,0);        WindowManager.LayoutParams layoutParams=window.getAttributes();        //设置宽度和高度        layoutParams.width= WindowManager.LayoutParams.MATCH_PARENT;        layoutParams.height=WindowManager.LayoutParams.WRAP_CONTENT;        //显示Dialog        dialog.show();            }        });

4、在styles.xml中设置dialog的样式

5、定义关闭与打开的动画效果

//结束<?xml version="1.0" encoding="utf-8"?>    //打开<?xml version="1.0" encoding="utf-8"?>

效果图：
